Heidi Montag denies that it exists, but her estranged husband Spencer Pratt is hoping to get $5 million for an alleged sex tape featuring the former stars of “The Hills,” TMZ reported today.

Pratt is reportedly in talks with Steven Hirsch of Vivid Entertainment, the adult film studio that released Kim Kardashian’s sex tape and will release the XXX debut of actor Laurence Fishburne’s daughter Montana.

Sources told TMZ that Vivid does not think $5 million is “an unreasonable price.”

Montag on Friday denied that the tape even exists. Friends of the reality star said she is “furious” at Pratt for claiming to have the footage, and that she would never allow herself to be filmed having sex because she is “extremely religious and concentrated on getting her life to where she wants it to be.”

Montag announced on July 30 that she filed for divorce from her “Hills” costar husband on July 30, after a little more than one year of marriage.

Pratt claims to have an “entire website’s” worth of footage of Montag, and that he was releasing the tapes to help Montag.

“When I realized how much Kim [Kardashian] was making [after her sex tape went public], my logic is this is the best thing I can do for my ex-wife,” Pratt said. “Kim is on the cover of Allure right now. Heidi isn’t on the cover of Allure.”
